Definitions

  • a common sound system utilizes only two to five channels and possibly even fewer amps and speakers.
  • Those systems playing a musical performance may have two channels dividing up many sounds. These sounds are usually amplified through two speakers.
  • This type of application does not recreate the original sound or create a sound similar to a live performance because multiple sounds travel through only a small number of channels, less channels than sounds utilized, and through a small number of speakers.
  • Those other types of systems are used for musical and non-musical applications, such as story telling, radio, talk shows, panel discussions and more.
  • a typical live performance, a concert or a studio recording for example, may have each instrument assigned to its own channel or to its own multiple channels.
  • a common multiple channel sound system may use 2 to 6 or even 8 or more channels to re-create sound.
  • stereo and “surround sound”
  • that concept creates a sound field for a pre-designated listening area. This is accomplished through the use of multiple speakers placed uniformly surrounding the listening area. Usually, there are front speakers and rear speakers. All sounds are divided among the speakers. Using electronic effects to fabricate realism, the sounds can be simulated for different listening environments. All effects are lost when the listener drifts away from the designated listening area. These conditions and restraints are unavoidable, because those systems set forth to re-create a single, pre-designated sound field.
  • a sound field is arranged by a recording engineer and permanently recorded onto the music during the mastering process for that song.
  • DVD-A DVD audio
  • SA CD super audio CD
  • guitar sounds would be heard more from the left front speaker and a bit from the center speaker. Keyboard would have about the same level from the center and the right speakers. All sounds would have some kinds of ambient feed back on the two rear speakers and extra low frequencies will come out from the subwoofer to add warmness to the sounds.
  • the prior art uses full range speakers and surround sound gadgets.
  • Those prior arts use a concept to try to re-create a sound field.
  • a sound field that is established by a recording engineer during the mastering of that song and can never be changed by the user. They do not re-create the sounds of the original recordings and never can they replicate a live performance.
  • the sound field is set by the recording engineer and cannot be changed. This sound field is designed assuming that the listening position is in the center, with all speakers surrounding it at somewhat equal distances. If the listener moves away from that position, the effects of realism are eliminated.
  • DVD-A has support from Panasonics and Warner Advance Media Operation. Panasonics has also formed a joint venture with Universal Music, presumably to promote DVD-A music. SACD is supported by Sony and Phillips. The current free MP3 sites and other sites that distribute music illegally are detrimental to legitimate music sales. As long as music resides in the stereo format, there is no way to prevent piracy.
  • the prior art uses speakers strategically positioned to replicate a reproduction of a sound field.
  • This sound field is supposed to create realism to correspond with the video of the single screen playing. For example, if a Sting missile is fired from the left of the screen and hits the target on the right, the sound tracing of the missile and the explosion can be done those speakers located on the left, center and right. But, when the missile is fired from the front left and hits a target at the right rear of the audience, the sound tracing and explosion still possible by the prior art, but the explosion scene will be on the front single screen — not very real to the human senses.
  • a new system which may be referred to as an MC or multiple channel system, fulfills needs of the prior art.
  • MC X Video employs a multiple screen technique to present video content.
  • the multiple screens can be in different forms. One is three flat-screens arranged in a trapezoidal configuration; the other is a dome screen similar to that in a planetarium. Others are multiple screens strategically located around the audience, with a main screen at front center.
  • a MC X audio system may split different sounds into different channels, allowing the sound to be played individually on separate speakers.
  • a song may be comprised of many instruments split onto several different channels.
  • the lead vocal may be on channel 1; back up vocal- channel 2; rhythm guitar- 3; lead guitar- 4; keyboard- 5; bass- 6; drums- 7, 8, 9, and 10, etc.
  • Each channel is a mono output to a speaker dedicated that channel's sound.
  • Each channel is dedicated to only the sound assigned to it. Thus, channel 1 will only play the sound of the lead vocal, and if the rest of the channels are shut off, only the lead vocal's singing can be heard.
  • Speakers are specially designed to handle a specific range of frequencies for that channel's sound only. Speakers for channel 1 and 2 will only need to handle the human voice, which is mid-range; channel 3 is for the guitar's frequency range, which is the mid- high range; channel 6 will be the low frequency for the bass, and so on. If speakers are not required to do so much, it is easy to design and make speakers that produce sound very close to the original sound being recorded. For the type of songs referenced in the above example, by placing ten different speakers around a small room, one can hear the audio experience of a song similar to a live performance.
  • This embodiment does away with stereo pair speakers and surround sound gadgets. Those devices do not re-create the original recordings and never can replicate live performance, which is one of the ultimate musical enjoyments for musical lovers. This embodiment processes and plays broadcastings and recordings of sounds so that a true re-creation of the original is achievable.
  • an MC X audio system can allow the user to create a sound field to cater to any personal preferences or to fit any listening area.
  • This embodiment processes and plays broadcastings and recordings of sounds so that it is as true to a re-creation of the original is achievable.
  • This embodiment provides an audio experience that is superior to any amplified, live performance.
  • MC X demonstrates its sound system along with the MC X formatted music in direct comparison with DVD-A.
  • the audiences that have heard the system are music industry executives, financial executives, recording and performing artists, music producers, various business executives, and specialized groups of students and professors at several educational institutions. The only audience reaction is astonishment and friendship. None can believe how simple the idea is but what a huge impact it makes on music as a whole. There has been no negative feedback; only shows of interest and offers of services and collaboration. Our cheap system sounds better than handmade high-end audiophile systems costing hundreds of times more.
  • MC X is a product line that is well crafted and carefully designed to provide leadership for the next 100 years. For the professionals, it provides solutions to create ultimate musical presentations. For record labels, it employs technology of the future and is designed as a piracy-proof system to restore music sales. For the rest of the multimedia and entertainment industry, it provides brand new ideas to make movies, shows, advertisements and presentations.

  • One embodiment transforms existing recorded sound into multiple channel sound tracks so that each track is a solo of musical sound that can be played on the MC X Audio System 1. Since the more channels there are on the system, the better the sound, this embodiment encourages the multiple channels to be scalable. For example: in an average rock band, there are 4-10 main instrument sounds. The percussion and drum sections occupy 3-20 sounds. If a speaker is dedicated to representing each instrument, the quality of sound is increased by magnitudes.

  • Figure 2 is a flow chart describing four types of MC X recordings.
  • Music recordings 31 are recorded by using one track per each sound. For primary tracks like vocal or lead instruments, many tracks can be assigned for that lead sound. This creates a more dramatic lead sound field when the music is being playback, and if applicable this can facilitate the re-creation of the lead sound moving around the room.
  • Sound recordings 33 are provided by sources such as, yet not limited to, story tellings, radio playings, educational programs, talk shows, panel discussions and special effect demonstrations. Each sound is recorded on a different track so that during play back the listener can have a perspective of different sounds since the sounds and voices come from different parts of the area or room for a true to live audio show. Advertisements 35 can also be used in the MC X system 1. A similar technique records commercials and ads so that the messages can be dramatic and the effect can be as close to live as possible.

  • the MC X sound system replays a song by transmitting each of the individual instruments or voices through a separate speaker powered by a separate amplifier. This way, each speaker is only required to handle a specific range of frequencies and is less likely to distort. The sound quality cannot be rivaled by current technology.
  • the MC X first generation product line will possibly produce all systems with a basic audio set having eight channels (eight amplifiers, eight speakers) to accommodate eight different sounds from a recording.
  • the eight channels may be designed to have one dedicated channel for bass, one for lead vocal, two channels for drums and four channels for accompaniments in a wide range of musical instruments from wood-winds to brass, guitar to keyboard and background vocals.
  • the heart of the MC X system is a processor operated by a proprietary software program. This program performs two functions:
  • the MC X proprietary amplifier contains multiple individual power amplifiers. This is also a very simple machine. Each amplifier is connected to its individual gain control and mute button to attenuate each instrument. There is a master volume control to provide overall loudness settings.
  • MC X speakers will be specially designed, each to recreate the sounds of a different instrument or voice.
  • Basic speakers will be designed specifically towards sound types (i.e. woodwind, brass, vocal, etc).
  • Upgrade speakers may re-create certain instruments (i.e. violin, trumpet, male tenor, etc).
  • High-end speakers may be designed to sound like a specific instrument or voice (i.e. 157 Fender Strat electric guitar played on a vintage Fender tube amplifier, Steinway concert grand piano, Celine Dion at Carnegie Hall, etc.).
  • MC X uses a new wiring system to do away with messy and tangled wires. Speaker wires are fused together to form ribbon with connectors at each end. Each section is 4-5 feet long. On each connector there are eight sets of contact specially designed to allow connections to each individual channel (1-8). The user places this ribbon system only one time around the listening area. Then the user can relocate each channel of sound as desired without moving a bunch of loose wires.
  • the MC X sound system is absolutely compatible with any entertainment system currently on the market. Although promoted as a stand-alone system, MC X can be utilized as an upgrade in system format to any current sound system, and all of the new features are still available. Any amplifiers or speakers currently owned can be used with the MC X player, and MC X wires to play MC X music. The only drawbacks are the sound quality (only MC X speakers are designed to reproduce specific sounds) and appearance (different styles or colors may have been used for different units).
  • All MC" song titles are stored in the master library server where all the songs are uniquely categorized by a special numeric coding system.
  • the server can talk to each MC X music player and identify each customer by the serial number through a broadband connection.
  • the server logs all the transfers as it sends them.
  • MC X can efficiently handle multiple sales of the same song to different customers all over the world.
  • An MC X song is sold to a customer using two methods:
  • a customer can take the hard drive out of the MC X machine and go to a music store to purchase song titles and download them onto the hard drive.
  • the security measure to prevent piracy of the music sales is in the MC X machine and the server. Both operate on proprietary software.
  • the user's MC X machine does not have a record function operable by the user. That makes it impossible for users to transfer song files from one machine to another.
  • a set of codes are encrypted and embedded into the data stream of the song and into the purchaser's MC X machine.
  • the purchaser's machine also is assigned a special code to receive that song at the beginning of the transfer. If need be, additional coding can be assigned at the middle of the transfer. The user's machine looks for these special numbers before it enables and completes the recording from the download. Without them, the program simply cannot record.
  • MC X works with record labels to restore the healthy sales of music over the Internet or otherwise.

Abstract

Un serveur stocke des fichiers numériques audio et vidéo coordonnés dans une bibliothèque et, sur requête, distribue des fichiers individuels à de multiples processeurs dédiés sous le seul contrôle unique du serveur. Des fichiers de musique ont des canaux vocaux et d'instrument spécifique séparés. Le processeur distribue des canaux uniques à des amplificateurs et à des haut-parleurs ayant des plages de fréquences contrôlées capables de reproduire uniquement des fréquences sur les canaux individuels. Des fichiers vidéo d'image sont projetés sur des écrans autour et au-dessus d'un public assis sur des chaises pivotantes. Des sons coordonnés émanent des haut-parleurs distribués sur les écrans. Un câblage de type bus s'étend à partir du processeur. Des câbles de haut-parleur individuel se connectent aux extrémités de conducteurs en faisceau.
